Spire smart pebble watches your breathing and mental health

Spire is small, comfortable and ready to help you calm the heck down. An attractive, $129 mindfulness and activity tracker, Spire looks nothing like any health gadget I’ve seen before. It’s resembles a small, gray rock and instead of sitting on your wrist, you clip Spire onto your waist band or bra and make sure the Spire pebble, which is about an inch in diameter and a half-inch thick, is facing in, resting gently against your skin or the waistband of your underwear. I thought this would be uncomfortable, but I soon forgot I was even wearing it.
